Page 19: Irrigation
The Irrigation Program screen consists of all settings for automatic irrigation starts. It depends heavily on the Water Run Time and Dosing Program screens and therefore they must be filled before irrigation can actually take place. The NMC-64 consists of 15 irrigation programs. IRRIGATION PROGRAM Program: Priority Const. - Page 20 Run Time is 30 minutes and the Delay is 45 minutes the second cycle will start 15 minutes after the end of the first cycle. • Valve # - The NMC-64 can operate valves in any required order; set the valve number, press enter, the following window will appear: Select ‘–‘...

Page 22: Water Run Time
NMC-64 Irrigation Setting an irrigation that is longer than 24H: An active irrigation will not change when the irrigation is longer than 24 hours there will be no changes in current sequence according to Cycle Days. Example 1: If cycle days is 1 and the irrigation length is 30 hours, the irrigation will repeat itself every 30 hours, so that it will be continues irrigation. -
Page 23: Dosing
P.Qty 0.00 0.00 The NMC-64 includes 10 predefined dosing programs. Each program can operate according to one of four methods. Each channel can be set to give a different amount, overlapping between the various channels is possible. Dosing programs can later be assigned to a valve or a group of valves in table IRRIGATION •... - Page 24 The total quantity of fertilizer that will be given is 5.0 * 3.5 = 17.5 liters (Gallons). 2.

Electrical grounding Electrical equipment can be destroyed or slowly damaged by voltage spikes, lightning hits, etc’. Proper electrical grounding in combination with the NMC-64 internal protections is essential to protect the system, reduce the risk of damage and prolong its lifetime. - Page 87 User & Installation manual Appendix • Length: Minimum 2.5 meters (8 feet), preferably 3-meter (10-foot). A longer ground rod will reach a soil with higher moisture content. Moist soil carries current much better than drier soil. • Single grounding: It is important that there is only one grounding location where a rod or series of rods are connected to each other using a ground wire.

Page 88: Ground Wire
NMC-64 Irrigation • Rod installation Drive the rod into the earth until about 10 cm (4 inches) is left above grade. If it is impossible to drive the rod to the proper depth, it is acceptable to lay the rod horizontally, 80 cm (2.5 feet) below grade. -
Page 89: What Should Be Grounded
3. Do not use light wires for these ground connections. They must carry heavy lightning currents, sometimes exceeding thousands of amperes. The galvanized plate of the NMC-64 is the ground reference for it. You may connect the heavy ground wire using spare screws on it. Do not use the shielding of sensor and low voltage wiring as lightning grounds. -
